Blue-green algae found at Carver Lake

Carver Lake users are advised to avoid contact with the lake until further notice due to the presence of blue-green algae. The beach remains closed due to the COVID-19 pandemic.

The presence of blue-green algae in Carver Lake was found Friday, July 10.

Not all blue-green algal blooms produce toxins; however, there is no way to predict if or when a bloom will produce toxins. For this reason it is best to avoid contact and stay out of the water.

If you believe you or your pets are experiencing adverse health effects due to contact with, or ingestion of, lake water or algae, seek medical attention immediately.
